Just wanting to do a simple rig set up, But it ends up not working correctly.

Well basically all i need to do is set up a very simple body rig, But the thing is need to set the weight to specific parts.
Well what happens is that i try and start off with a blank slate so that way i can set all of the verticies i want to which bone i want.
Well for some reason even though that it shows on the weight paint that nothing is attached to the bones. (And i’ll even try and remove all weight for all bones)
It still ends up being attached to odd parts of the body.

Is there a more simple parenting set up for a rig, or am i just doing something wrong.
